481,611. Renewed September 23, 1933 3 Claims. (c1. 147-47) The present invention relates to basket-making machines; and an object thereof is to provide in such a machine co-operating basket forms relatively rotatable to shape the baskets in circular form; and further, to provide in such a machine improved members relatively movable on antifriction devices; and further, to provide such a machine improved in various respects hereinafter appearing. V

These objects are attained by, and the invention finds preferable embodiment in, the structure and mechanism hereinafter particularly described in the body of this specification, and illustrated by the accompanying drawings forming a part hereof, in which: V

Figure 2 is a front elevational view, partly in axial vertical section, of a convex basket form;

Figure 8 is a transverse sectional view of parts of the same takenon line 8-8 of Figure 7;

Figure 9 is an end view of a convex basket form with adjacent parts and showing a fragment of the basket-making material in position to be formed by the basket forms and showing pressure bars for engaging hoop-making strips;

Figure 10 is a view of pawl and ratchet mechanism for turning one of the basket forms.

Figure 11 is a radial sectional view of parts of the concave member as shown in Figure 3, much enlarged.

In these drawings is illustrated a basket-making machine of the general type shown in Patent No. 619,182 to William Jackson.

The base 1 of this machine is hollow forming a compressed fluid tank 2 which contains a pair of fluid compressing cylinders or pumps disposed side by side, one (3) of which is shown in vertical section in Figure '6, the other cylinder 4 being 5 located on the far side thereof in said view.

These cylinders contain piston heads 6 with piston rods 7 connected thereto andto the straps 8 bearing on the eccentrics 9 on the driving shaft '10, these piston heads being provided with check valves 12 and the cylinders with opposite 60 check valves 11 through which the fluid is pumped into the tank. I

On a way 13 on thebase a carriage 14 is slid in opposite directions by a compressed fluid cylinder 15-supplied through a pipe 16 from the 5-, tank and controlled by a valve indicated at 17 having an operating arm 18, this cylinder containing a piston having the piston-rod 19 connected to a standard 20 of the carriage. A shaft-v 21 rotatable in bearings 22 on the bases standard 70 V 24 is turned by degrees by a pawl 25 mounted on an arm 26 turnable on this shaft, this pawl engaging a ratchet wheel 27 keyed on said shaft.

A convex basket form'28, in shape a slightlytapering truncated cone, is splined'at 29 on shaft 75 21 andturns in a bearing 30 on the carriages standard 20. V V a v A standard 31 on the carriage'14 isspaced from standard 20 thereon and carries a compressed fluid cylinder 32 containing a piston 30*- head 33 having a hollow piston rod 34 carrying a concave basket form designated generally 35.

A head 36 has an interiorly threaded portion 37 screwed on the hollow outer end of rod34, and an exteriorly threaded portion 38 screwed into the base member 39 of the concave basket form, as particularly shown in Figure 3, the base member 39 having an outwardly diverging hollow shaping portion 40. A circular boss 4l'projects from the center of the base member 39 and has secured 9Q thereto as by screws 42 a bearing ring 43 on which is turnably mounted a circular bottom member44 which is held in place by a retaining flange 45 of said bearing ring.

The shaping portion 40 of the base member is 5 provided adjacent the front thereof with'a plurality of angularly spaced sockets 46 in which are i secured the members 4'7 as by screws 48; and these members 47 have concave ball-receiving sockets 49 in the inner faces thereof. A ring 100 has a cirm cular ball-race 50 in the outer surface thereof, and

is turnably mounted on ball-bearings 51 seated partially within the race and partially within the ball-receiving sockets 49.

The basket-making material comprising a plu- 5 rality of radially extending thin strips 52 connected at 53 in their middles, being-positioned on the support 54, and the carriage 14 with the convex basket form 28 being moved by the piston rod 19 to, and held in, the position seenin Figure m of valve 17 The pipe 86 comprising ailexible, portion 87 1, the concave basket form 35 is moved by the piston rod 34 toward convex basket form 28,

thereby bending the said material over form 28 and inside form 35 to form it into basket shape.

The carriage 14 is now slid by piston rod 19 toward the left hand side of Figure 1 carrying the forms to a position beneath a staple driving mechanism designated generally of common form, (such, for instance, as is shown in said Jackson patent) comprising the pitman 56 connected to the crank 57 on a driving shaft 58 and carrying at the lower end staple driving plunger-s in the staple chutes 59 mounted on the head 60 of the bases standard 24. This stapling mechanism operates through an opening 103 in the top of the concave form.

The machine is driven byshaft 10, as-by a belt carried by its pulley 61, and a belt carried by pulley 62 on said shaft and pulley 63 on shaft 58 operates the staple driving mechanism, and through the connecting rod 64 pivoted to the crank 65 of shaft 58 and to the ratchet mechanisms arm 26 turns the shaft 21 step by step.

By this operation the convex form 28, and the :ring and bottom members 100=and44 respectively of the concave form 35 turn together car"- rying the basket forming material with them; and the head 35 is held from turning by a rod 65 slidable in bearings 67 on the-earriages'arm A shaftv 68 is turnably mou-nted ina bearing 69.

on upright 24 and carries blocks 70 tight hereon.

These blocks carry pressure bars .71. When the pedal 72 swingablymounted at '?3 on the base 1 and counter-weighted at 74 is pressed down; its

"rod '75 swings the bell crank lever 76 causing rod?- 77, pivoted thereto and to an arm '53 of one of said blocks, to turn shaft 68 and these blocks and raise the bars 71 from form 28 so that hoop-forming'strips -79 :may be inserted between the free ends of the bars and the bent over strips 52 of the basket-making material. r V

The pedal being released the hoop-strips 79 are fed circularly bythe rotation of form 28"into positions to be stapled by the mechanism 55 to the strips 5210f saidmaterial.

When the basket has been 'thusiormed, the carriage 14 is again moved to the positionseen in igure 1 and the basket is removed from the machine. A lever 80 and its rod 81 serve to operate, a clutch indicated at 82 wherebythe pulley 62 is rotatingly connected to and. released from the driving shaft 10; :and a lever 83 and its connecting rod 84 having an upwardly extending mem-- ber 85 pivoted to the forwardly extending arm 18 es to openand close this valve.

leads from the compressed fluid tank 2 to the cylinder 32. i

shown in Figure 5, the shaping side portion 40 of the base member 39 is eliminated and replaced by a plurality of angularly spaced arms 88 secured to the edge of the base member 39 as by screws 89. These arms have near their outer ends ballr ceiving sockets 49 which function the same as the sockets 49 shown in Figure 3. Figure 5 also illustrates a method of mounting the bottom plate 44 on ball-bearings 92, which are disposed-within complementary circular races 93 on the bottom plate and 94 on an auxiliary plate 95 secured to the base member.

a In order that the bottom of the basket may be forced slightly into the concave opening 96 in which the pin 99 is diametrically inserted. The

plunger 97 is normally'urgedoutwardlyby the pressure of a spring 106 locatedwithin shaft 34 and bearing against the plug 93 and a collar 107 securedonthe plunger. y i
